Bike,
US Army Warrant Officers are highly skilled technicians whose primary skill is out smarting RLO's....Real Live Officers.
As you might not know.....qualifying scores to enter Warrant Officer School exceeds that of Officer Candidate School (OCS).
Only the US Army would craft a system that puts the less bright in command of the brighter ones.....with expected results.
Perhaps there are some similarities between the British Army and mine after all.
